 # WarBot2020
 Bootleg version of "WorldWarBot 2020" done in Java and without a map.
 
-Usage:
 ```
-executable.jar soglia_popolazione verbose n_guerre
+Usage: <main class> [-hv] [-m=<max_population>] [-n=<n_wars>] [-s=<source_file>]
+  -h, --help             display a help message
+  -m=<max_population>    filter cities for max population (default 50000)
+  -n=<n_wars>            sets number of wars to simulate (default 500)
+  -s=<source_file>       load data from a specific file (default data.txt)
+  -v                     only simulate one war (default false)
 ```
-- soglia_popolazione is an integer (default 12000)
-- verbose is a boolean. true gives you the detailed output of a single war, false gives you generic statistics on n_guerre wars (default true)
-- n_guerre is the number of wars to simulate (default 500)
 
-The program will load the default values if you don't always put all three parameters.
+Watch out for the -v flag! If you don't include it, the program will simulate multiple wars and give you win statistics, so use that if you only want to see a single outcome.
 
 # Data collection
 The program reads coordinates and populations from data.txt in this format:
